- restoration of print quality - from 400 rubles.
Consider typical faults Envy 110 and show you how to disassemble the device.
Screen control repair
Due to the small thickness when printing touch screen rises to make room for the paper to exit. It is not uncommon for the HP Envy 110 to have a broken screen-raising mechanism. Instead of a smooth rise, the screen twitches and freezes half way. “Screen Error” appears on the screen because the printer is no longer working.
The HP Envy 110 Motor Module consists of the motor itself, an encoder, a board, and a cable. Repair of the HP Envy 110 screen position control mechanism consists in replacing one of the motor modules. After replacement, the screen opens and closes.
Drawer Control Repair
The HP Envy 110 printer starts moving the screen and drawer as soon as it is turned on. If the paper drawer is not working properly, such as jerking, the printer will not print. Moreover, the tray cannot be removed - without it, the printer will also not work. Primarily due to the fact that the tray switches the sensor flag.
A problem with the tray is possible, firstly, due to a breakdown of the engine, and secondly, due to a malfunction of the motherboard.
The drawer control motor is located under the board on the right.
We change the entire structure along with the encoder.
HP Envy 110 carriage jam
The HP Envy 110 received for repair had a malfunction: a few seconds after turning on, the carriage stops and the message “the carriage cannot move, the carriage is stuck, remove the obstacle ...” Cleaning the encoders did not help. The cleaning of the parking lot did not help either. The culprit for the carriage jamming was a faulty carriage motor.
The carriage motor from the HP Deskjet Advantage 5525 MFP was taken as a replacement.
The message "carriage jam" means a lot of problems with incorrect positioning of the carriage. For example, when there is no speed feedback from the encoder strip. The sensor on the carriage and the control board are responsible for processing this signal with a clean tape. If the sensor works, then the cause is a faulty main control board. 
Repair in this case is most likely impossible.
HP envy 110 won't turn on
If the HP envy 110 MFP does not turn on when you press the power button, there is a problem with the main control board or power supply.
A specific example with a burned out HP envy 110 power supply: The MFP did not respond to the power button, although the power indicator was blinking.
In the HP envy 110, the power supply is made as a separate device, which is located inside the case on the left side. The Envy 110 power supply has 2 supply voltages: 32V and 24V. The body of the block is glued, so it is very inconvenient to disassemble. 
After opening the case, we find typical scheme switching power supply. 
In our particular case, an electrolytic capacitor exploded in the primary circuit of 120 uF at 400V. Moreover, the electrolyte flooded the entire circuit and burned 2 more capacitors.
After a thorough cleaning and replacement of the capacitors, the power supply worked. The MFP began to turn on, but hung at the initialization stage. To return the MFP to working capacity, it was necessary to reset the control board.
HP Envy 110 disassembly
First, remove the side covers, which are attached to the latches.
Raise the scanner and remove the top cover covering the main board.
Then remove the top caps.
On the right are 2 engine modules. One raises the screen, the second extends the paper bin.
To get to the modules, you need to remove the main board.
The hardest part is removing the scanner. To do this, disconnect the cables, press the latch of the lift bracket (the place is shown by the arrow), move it inside the scanner, release the bracket on the right and left, remove the scanner.
We unscrew all the screws securing the top cover from above and remove the cover.
The circle indicates the carriage motor that we will be replacing.
When disassembling the carriage, we check the carriage position sensor using the encoder marks, the microcircuit for reading and controlling the signals of the cartridges.

HP DesignJet 110plus nr. How do I clean the print heads on this plotter? Stopped printing yellow head. and got the best answer
Answer from Alisa Kiryanova[guru]
this is the control panel of this plotter
It has 3 types of print head cleaning:
for soft cleaning: With the plotter turned off, press the Power button while holding it 2 times, press the Cancel button
For Medium: Same thing, just press the Continue Button one more time (it's number 3 in the photo)
For heavy cleaning: Same as for soft cleaning, only press the Continue button 2 times
cleaning should be done from soft to heavy and no more than 1 for each ... so as not to damage the oven. head
There is also an instruction, but it is in English:
Answer from Bruho[guru]
You take out the cartridge and calmly wipe the printing side with a paper towel. If the paint is dry it will help. If it's over, then no. And then I started and ended with this ... throwing the printer into a landfill. Something went wrong with the electronics. parts were not found. repairs are more expensive than new.
Answer from Anton Klopov[newbie]
By the way, we also have a plotter - so I'm wondering - what is the best way - so that it is constantly turned on or every time tuij turn it on again and do the cleaning ???
Answer from Boris Batchaev[active]
Inkjet printers MUST operate continuously.
From the nuances:
tested paint (if not original), spare heads, constant temperature and humidity in the room, no drafts, wet cleaning 1-2 times a day, no dust, power stabilizer (preferably Smart UPS), paper with low level dusting (again, if not from the list recommended by HP).
If there is a CISS - once a year, a complete flushing of the ink supply system with special solutions.
And don't forget to shake the cans...
